" erence being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

Myinvention relates to a governor for pumping-engine, as described in a separate application for patent; and it consists in the construction and arrangement of the devices connectwhat I claim as new, and desire to secure by ing the weighted beam with the water-pipes, as will be hereinafter more fully set forth.

In the annexed drawing,-Figure 1 is a side elevation of the governor embodying my invention. Fig. thereof.

A is the foundation; B, the cylinder, with steam-chest G. D is the valve, with valve- 2 is a vertical section of a part stem a connected to the graduated bean pivoted in the standard E. His the movable weight, with roller 12 and set-screw d. h is the stop in the beam, all of said parts being precisely the same as in my other application above referred to. K represents a pipe, having exterior screw-threads on its lower end to be connected with the water-main. This pipe extends downward from a plate, L, on the foundation, and on top of this plate is an ordinary stuffing-box, J, with packing at, through 'lhe stuffing-box J forms a water-tight joint to prevent the escapeof water, and the pressure in the water-mains operates on the rod 1, and through it on the weighted beam and valve, to regulate the pump in the same manner and for the same purposes as described in my other application.

Having thus fully described my invention,

Letters Patent, is

In a pump-governor, operated by the pressure of water in the mains, the pipe K, stuffing-box J, and rod I, in combination with the pivoted beam G connected with the valve of the pumping-engine, and provided with the self-acting weight H, all substantially as and for the purposes herein set forth.
